Abstract

The mixed-ligand complexes [Cu(II)(HisLeu)(phen)](+) (1) and [Cu(II)(HisSer)(phen)](+) (2; phen=1,10-phenanthroline) were synthesized and characterized. The intercalative interaction of the Cu(II) complexes with calf-thymus DNA (CT-DNA) was probed by UV/VIS and fluorescence titration, as well as by thermal-denaturation experiments, and the intrinsic binding… (More)
